Description

Technical Field

[0001] The invention relates to the technical field of solid waste incineration, and in particular to a solid waste gasification incineration device. Background Art

[0002] Solid waste refers to solids produced in the process of production, life and other activities that have lost their original utilization value or have not lost their utilization value but have been discarded or abandoned. Since solid waste can easily cause harm to the environment, it is generally necessary to treat it in a corresponding way, such as thermochemical treatment. Thermochemical treatment methods mainly include incineration, pyrolysis and gasification. When traditional gasification incineration equipment is burning solid waste, the incineration efficiency can be improved by adding oxygen to the incineration area.

[0003] At present, when traditional gasification incineration devices perform gasification incineration on solid waste, they directly throw the solid waste into the incineration area. Although the gasification incineration treatment can be effectively carried out, the solid waste accumulated inside the incineration area and the solid waste in the concentrated state of incineration cannot fully contact with the gas and flame, and the contact area is small, so that the efficiency is low during the incineration process. The treatment method of the existing gasification incineration device generally adopts a stirring method to stir the accumulated solid waste. Since the stirring mechanism needs to stir the solid waste, its stirring parts need to be exposed to the combustion area and are in the flame for a long time, which can easily reduce its service life. In addition, the solid waste is driven by stirring, and there is a lack of support and suspension treatment for the solid waste, so that it is not easy for the flame to penetrate the interior of the solid waste to form the problem of accelerated gasification incineration. Summary of the invention

Through the setting of a shaking component, the solid garbage above the grate can be shaken, which can not only disperse the solid garbage in a concentrated state of incineration in a wavy state, but also support the dispersed solid garbage, thereby increasing the contact area between the bottom of the solid garbage and the gas, and increasing its gasification and incineration efficiency. This solves the problem that most of the incineration devices in the prior art use a stirring method to drive the solid garbage, and the stirring component needs to be set in the center of the combustion area, so that it is easy to reduce its service life when it is in the flame for a long time.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Embodiment 1:

[0042] Refer to the attached Figure 1-10 A solid waste gasification incineration device comprises an outer furnace body 1 and an inner furnace body 2 fixedly installed inside the outer furnace body 1, a feed port and an ash discharge port are respectively arranged at the top and the bottom of the inner furnace body 2, and the feed port and the ash discharge port are extended to the outside of the outer furnace body 1, an air supply pipe 3 is fixedly connected to the bottom of the outer furnace body 1, and a fan body 4 with adjustable speed is installed at one end of the air supply pipe 3, a grate 6 is fixedly installed inside the inner furnace body 2, a plurality of primary air inlets 7 are opened at the bottom of the inner furnace body 2, and a plurality of secondary air inlets 8 are opened on both sides of the top of the inner furnace body 2;

[0043] The setting of the feed port makes it convenient for the staff to place the solid waste to be incinerated into the inner furnace body 2 for incineration, and inject gas into the inner part of the outer furnace body 1 through the air supply pipe 3 through the fan body 4, and enter the inner furnace body 2 through a plurality of primary air inlets 7 to form an incineration process, and then discharge part of the gas into the inner furnace body 2 through a plurality of secondary air inlets 8 above, forming a pressurized incineration smoke process, thereby realizing the gasification and incineration treatment of the solid waste;

[0044] A set of heat-conducting fins 5 are fixedly connected to both sides of the inner furnace body 2, and both sets of heat-conducting fins 5 extend to the interior of the inner furnace body 2;

[0045] The heat conducting fins 5 are connected to conduct the high temperature inside the inner furnace body 2 to the compartments of the outer furnace body 1 and the inner furnace body 2, so as to quickly heat the gas, thereby improving the gasification and combustion performance of the smoke, and having good heat conduction function;

[0046] The inner furnace body 2 is provided with a shaking assembly 9 for shaking the solid waste above the grate 6, and the back of the outer furnace body 1 is provided with a pressurizing assembly 10 and a driving assembly 11 for driving the shaking assembly 9 and / or the pressurizing assembly 10, and the driving assembly 11 includes an electric telescopic rod 111;

[0047] By setting the electric telescopic rod 111 in the driving component 11, the shaking component 9 and / or the pressurizing component 10 can be driven, which has a good linkage function. By setting the pressurizing component 10, the gas entering the furnace body can be pressurized, thereby improving its gasification and incineration supply strength and accelerating the garbage incineration performance. By setting the shaking component 9, the solid garbage above the grate 6 can be shaken, which can not only disperse the solid garbage in the concentrated state of incineration in a wavy state, but also support the dispersed solid garbage, thereby increasing the contact area between the bottom of the solid garbage and the gas, and increasing its gasification and incineration efficiency. This solves the problem that most of the incineration devices in the prior art use a stirring method to drive the solid garbage, and the stirring component needs to be set in the center of the combustion area, so that it is easy to reduce its service life when it is in the flame for a long time.

[0048] Refer to the attached Figure 7 , Figure 8 and Fig.10 The shaking assembly 9 includes a plurality of shaking frames arranged inside the inner furnace body 2 and a shaking member 93 for shaking the shaking frames up and down;

[0049] By setting the shaking member 93, a plurality of shaking racks can be shaken in a wave-like state, thereby further improving the dispersion effect of the solid waste on the top of the grate 6 and increasing the gasification and incineration efficiency;

[0050] The shaking frame includes a U-shaped sliding frame 91 slidably connected to the inner furnace body 2, and a plurality of U-shaped supporting blocks 92 are fixedly connected to the top of the U-shaped sliding frame 91, and the tops of the plurality of U-shaped supporting blocks 92 extend to the top of the grate 6;

[0051] The up and down movement of the U-shaped sliding frame 91 can drive a plurality of U-shaped supporting blocks 92 to move up and down. The up and down movement of the plurality of U-shaped supporting blocks 92 can shake the solid waste above the grate 6, which can not only disperse the solid waste in the incineration concentrated state, but also support the dispersed solid waste, thereby increasing the contact area between the bottom of the solid waste and the gas, and increasing the gasification and incineration efficiency.

[0052] The tops of several U-shaped supporting blocks 92 are slightly higher than or equal to the height of the grate 6, so that when the solid garbage on the top of the grate 6 is incinerated, the burning of the U-shaped supporting blocks 92 by the flame is reduced, thereby increasing the service life of the U-shaped supporting blocks 92. This solves the problem that most of the incineration devices in the prior art use a stirring method to drive the solid garbage, and the stirring component needs to be set in the center of the combustion area, so that it is easy to reduce its service life when it is in the flame for a long time.

[0053] Refer to the attached Figure 7 and Figure 8 The shaking member 93 includes two triangular blocks 931 sliding on the inner bottom of the outer furnace body 1, one side of the two triangular blocks 931 is fixedly connected with an operating rod 932, one end of the two operating rods 932 extends to the outside of the outer furnace body 1, and a connecting plate 933 is fixedly connected between one ends of the two operating rods 932, and the connecting plate 933 is detachably connected to the driving end of the driving assembly 11;

[0054] The connecting plate 933 is detachably connected to the driving end of the driving assembly 11, which facilitates the driving of the electric telescopic rod 111 in the driving assembly 11, and the connecting plate 933 can be moved horizontally, and then the two triangular blocks 931 can be driven to move synchronously in the same direction through the two operating rods 932;

[0055] Through the movement of the two triangular blocks 931, the U-shaped sliding frame 91 can be lifted, and the gravity of the U-shaped sliding frame 91 and several U-shaped supporting blocks 92 can form an up and down reciprocating motion, forming the shaking of the solid waste, further increasing the contact area between the solid waste and the gas, and improving the solid waste incineration performance of the pressurizer;

[0056] The bottoms of the plurality of U-shaped sliding frames 91 extend to the interior of the outer furnace body 1, and both sides of the inner walls of the plurality of U-shaped sliding frames 91 are fixedly connected with a toggle shaft 934;

[0057] When the triangular block 931 moves horizontally, the toggle shaft 934 can be squeezed through the inclined surface, so that the toggle shaft 934 can move along the inclined surface of the triangular block 931 to form an up and down movement, thereby driving the U-shaped sliding frame 91 to move up and down.

[0058] Refer to the attached Figure 8 The bottom of the triangular block 931 is provided with an embedded hole, and a sliding block 935 is slidably connected inside the embedded hole, and the sliding block 935 is slidably connected to the inner bottom of the outer furnace body 1, and a pressure sensor 936 is installed between the sliding block 935 and the embedded hole;

[0059] The triangular block 931 is slidably connected to the inner bottom of the outer furnace body 1 by a sliding block 935, which improves the smoothness of the horizontal movement of the triangular block 931. A pressure sensor 936 is provided between the sliding block 935 and the triangular block 931, so that the force of the triangular block 931 to move the shaking frame upward can be detected, and then the combustion status of the solid waste in the furnace can be understood, which improves the convenience of its solid waste replenishment and has a self-detection function;

[0060] The method solves the problem that the garbage replenishment method in the prior art generally uses human eyes to observe the height of the flame or the situation in the furnace to understand the garbage incineration situation, but due to the high temperature in the incineration area, it is easy to cause burns to the face, making it inconvenient to observe closely, affecting the subsequent judgment of the garbage incineration situation;

[0061] During the combustion process of solid waste, the weight of the solid waste will gradually decrease. When the solid waste drops to the set threshold, it is detected by the pressure sensor 936 and notified through the external alarm, thus forming an automatic alarm.

[0062] Embodiment 2: Based on embodiment 1, the difference is that;

[0063] Refer to the attached Fig. 9 and Fig.10 The pressurizing assembly 10 includes a negative pressure cylinder 101 fixed to the back of the outer furnace body 1 by a bracket and a piston plate 103 arranged inside the negative pressure cylinder 101. One end of the negative pressure cylinder 101 is fixedly connected to a pressurizing pipe 105, and one end of the pressurizing pipe 105 extends to the inside of the outer furnace body 1. The inside of the piston plate 103 is fixedly connected to a plurality of exhaust pipes 106, and a check valve is installed on the plurality of exhaust pipes 106 and the pressurizing pipe 105.

[0064] Through the reciprocating movement of the piston plate 103, the external gas can be extracted into the negative pressure cylinder 101 through the exhaust pipe 106, and the extracted gas can be pressurized into the interior of the outer furnace body 1 through the pressurizing pipe 105, forming a gas pressurization operation, further improving the solid waste gasification and incineration effect, and having a multi-level oxygenated gasification and combustion function;

[0065] Two sets of one-way valves are provided to perform one-way control on the pressurizing pipe 105 and the exhaust pipe 106, so that when the piston plate 103 is unfolded, the negative pressure state inside the negative pressure cylinder 101 can be used to extract gas through the exhaust pipe 106, and the extracted gas can be squeezed by the contraction movement of the piston plate 103, and then the extracted gas can be pressurized into the furnace body, thereby improving its gasification and incineration performance.

[0066] A driving rod 102 is slidably connected to the interior of the negative pressure cylinder 101 through a bracket, one end of the driving rod 102 is fixedly connected to the piston plate 103, one end of the driving rod 102 is fixedly connected to an auxiliary block 104, and the auxiliary block 104 is detachably connected to the driving end of the driving assembly 11;

[0067] By starting the electric telescopic rod 111 in the driving assembly 11 , the auxiliary block 104 can be driven, and then the piston plate 103 can be driven to telescopically reciprocate through the driving rod 102 .

[0070] The top and bottom of the connecting frame 112 are rotatably connected with the adjusting shaft 113, and one end of the two adjusting shafts 113 is fixedly connected with a U-shaped limit block 114. Through the rotation of the two U-shaped limit blocks 114, the connecting plate 933 in the shaking component 9 and the auxiliary block 104 in the pressurizing component 10 can be wrapped and locked, and the start of the electric telescopic rod 111 can drive the connecting plate 933 and the auxiliary block 104 to perform synchronous telescopic movement, forming a synchronous driving operation of the shaking component 9 and the pressurizing component 10, which has a good linkage function, is convenient for shaking the solid waste during combustion, and synchronously pressurizing the gas entering the inner furnace body 2, further improving its gasification and incineration effect, and solving the problem that the incineration device in the prior art cannot handle the suddenly generated smoke when turning over the solid waste during the incineration process, thereby affecting its gasification and incineration effect;

[0071] By rotating one of the U-shaped limit blocks 114, the driving end of the driving component 11 can be connected to the shaking component 9 or the pressurizing component 10 to form a separate driving operation of one of them, further improving the functionality and practicality of the driving component 11.

[0072] Embodiment 4: Based on embodiment 1, the difference is that;

[0073] Refer to the attached Figures 3 to 6 Two flow control components 12 for controlling the flow of the two sets of secondary air inlets 8 are arranged at the top of the outer furnace body 1. The flow control components 12 include a plurality of conical blocks 121 for inserting into the interior of the secondary air inlets 8. The interiors of the two sets of secondary air inlets 8 are both conical in shape.

[0074] The flow control component 12 is provided to control the gas inside the outer furnace body 1 entering the inner furnace body 2 through the secondary air inlet 8 to meet the gasification and incineration treatment work with different gas flow rates and different airflow injection pressures.

[0076] By setting the adjusting member, the position of the adjusting frame 122 can be adjusted, and the conical block 121 can be driven to move along the axial direction of the secondary air inlet 8, which can not only adjust the flow rate of the internal gas of the outer furnace body 1 entering the inner furnace body 2 through the secondary air inlet 8, but also adjust the gas pressure entering the inner furnace body 2, thereby realizing the airflow injection effect, facilitating the gas entering the inner furnace body 2 through the secondary air inlet 8, and increasing the pressure of the smoke inside the inner furnace body 2, further improving its solid waste smoldering performance, and enhancing its solid waste incineration efficiency;

[0077] The adjusting member includes a hinge seat 123 which is slidably connected to the inner wall of the outer furnace body 1, and an inclined transmission frame 124 is hinged between the hinge seat 123 and the adjusting frame 122.

[0078] By manually rotating the adjusting rod 125, the hinged seat 123 can be driven to move forward and backward, and then the tilted transmission frame 124 can be driven to move in a fan shape. Through the fan-shaped movement of the transmission frame 124, the position of the adjusting frame 122 can be adjusted to adjust the air inlet aperture of the secondary air inlet 8, thereby further improving its smoke combustion effect.
